Vitamin B12

Vitamin B12 is a water-soluble vitamin that plays an important role in the production of your red blood cells. It also helps in maintaining the normal functioning of your brain and nervous system. It’s found in several foods including meat, fish, eggs, dairy products and some fortified breakfast cereals.

You need Vitamin B12 to help maintain your nerves’ myelin sheath. If you are deficient in vitamin B12 you can get symptoms that are similar to some of the symptoms of MS, such as fatigue, weakness, numbness or tingling and problems with memory. For this reason, if your doctor suspects that you may have MS, part of the NICE diagnosis guidelines includes a blood test to rule out vitamin B12 deficiency as a cause of your symptoms.

Some studies have found a higher rate of vitamin B12 deficiency in people with MS than in people without MS. One study found that although the levels of B12 in the blood were normal in people with MS, the levels in their cerebrospinal fluid were lower than usual, although the reason for this difference was not clear. Other studies have found no link between vitamin B12 deficiency and MS.

If a person with MS has vitamin B12 levels that are within the normal range there’s no research evidence suggesting that taking vitamin B12 supplements would benefit them. However, despite the lack of research evidence, some people with MS use monthly injections of vitamin B12 as a treatment for fatigue.

Vitamin B12 supplements were one of the elements of the Cari Loder regime.
